This invention relates to glass holding members, and more particularlyto a metallic sash for holding heavy plate glass of the type used instore front construction.

The primary object of the invention is to provide a sash which'exerts noscrew clamping pressure on the glass and which comprises inner and outerglass contacting members connected and held against the glass withsuflicient resiliency to absorb sudden stresses exerted on the glass bywind pressure or otherwise.

Other objects and advantages of the invention will become apparent asthe description proceeds, reference being had to the accompanyingdrawing, in which:

Figure l is an enlarged cross sectional view of one form of sashembodying the present invention;

Figures 2, 3 and 4 are similar views of other forms of the invention;

Figure 5 is a perspective view ofthe resilient bracket used inconnection with the forms shown in Figures 1 and 2;

Figure 6 is a fragmentary sectional view of a slightly modified form ofFigure 1; and

Figure 7 is a perspective view of the resilient bracket used inconnection with the forms shown in Figure 3.

Referring to the drawing and particularly to Figure 1, the sash includesan inner member I and an outer member 2 which are connected to eachother to hold a pane of glass in a manner hereinafter described. In thebetter grade of store fronts these members are made of extruded metalwhich has a more attractive appearance than rolled or drawn metal. Theinner member I has an offset downwardly turned'flange 3 which isadaptedto be moved into position against a pane of glass 4. A horizontalportion 5 of the inner member extends outwardly and terminates in anupright foot member 6 which is adapted to rest on a base member I, whichlatter extends entirely across the frame or sill member 8 of the windowopening.

The outer member 2 preferably comprises an upright portion 9 from whichis offset a glass engaging flange I 0 similar to the inner glassengaging flange 3. A horizontal part i I extends outwardly andterminates in an upright foot member l2 which rests on the base member 1similarly to the inner foot member 6. Beneath the horizontal member H, afastening flange l3 extends downwardly into the space outlined by thehorizontal member and the foot member l2. It will be understood that theinner and outer sash members and the fastening flange are continuousthroughout the length of the window opening.

Spaced at intervals along the sash, as for instance at 12 inch centers,are connecting brackets which in this instance comprise, as best shownin Figure 5, members having a U-shaped'central portion 20 having itsfree ends 2| and 22 turned outwardly to formv an inner shoulder 23and-an outer shoulder 24. The inner shoulder23 has 1 downwardly struckwedge-shaped surfaces; 25 formed therefrom. -In the assembly, as.--shownin Figure 1, the inner shou1der'23 is adapted .to be held in abuttingrelation to the horizontal portion 5 of the inner glass holding memberby 5 coaction of a screw 26 and an elongated wedge shaped nut 21, theupper surface of which is cut at an angle supplementary to the slope. ofthe wedge shaped surfaces 25. v

The outer shoulder 24 of the resilient bracket is bent downwardly toform an upright portion 30 which extends outwardly from either side ofthe bracket. The upright portion has holes 3| formed therein in theaforesaid outwardly extending portions for the reception of screws 32. 5These screws are adapted to be engaged in nuts 33 so that the bracketmember is fixedtothe fastening flange l3 of the outer sash.

The entire sash assembly is held in position on the window frame 8 bymeans of screws 34 which extend through the bight portion of theresilient bracket, the base member 1, and into the window frame. It willbe seen from the above that when it is desired to fit a pane of glass,the entire sash is assembled by drawing up screws 32 and 34, and looselypositioning screw 26 in its wedge shaped nut 21. The desired degree ofpressure is then exerted on the glass by moving the inner sash member Iinto engagement with the pane. This member is then retained inits p 0desired position by finally tightening the screws 26 so' as to draw thewedge shaped nuts 21 against the corresponding wedge surfaces 25..

It will be obvious that sudden shocks and strains on the glass will betaken up in the resilient connecting bracket 20 which permits a slightflexibility, or relative movement between the inner and outer sashmembers. It has been found that the sash members themselves can be madesubstantially rigid and that the bracket will afford the necessaryresiliency to properly set the glass.

In the event that further flexibility of the sash is desired, theupright portions of the inner and outer sash members, or one of them,may be weakened as at A, along a line parallel to its up per surface, asshown in Figure 6, so as to provide definite axes of flexure about whichthe sash members may give to a force exerted on the glass. 7

In the form of sash shown in Figure 2 the outer sash member issubstantially the same as that shown in Figure 1, and the referencenumerals, therefore, are the same. In this instance, however, the basemember j'l has an upwardly extending inner surface 40 which in turn isbent to form a gutter 4| substantially parallel to the bottom surface.The inner glass contacting part comprises an upright foot member 42, ahorizontal portion 43, the end of which is bent "upwardly into a glassengaging surface 44, which latter terminates in an inwardly, anddownwardly I extending part 45, the end of which overliesthe extremityof the gutter member 4| so as to give the inner sash a continuous andfinishedappean' ance. .The final setting screw 46 in this instance isconcealed beneath the gutter portion 4|, and, similarly to thepreviously described form, has threaded engagement, with a wedge shapednut 41. The resilient bracket in this form is identical with that usedin connection with Figure 1, so that the description thereof need not berepeated. .Access to the setting screws 46 is had through holes 48 inthe inner sash member.

When it is desired to set a pane of glass in a sash of this form theentire sash is assembled, leaving the screws 46 loosely engaged withtheir wedge shaped nuts. The desired pressure is then exerted on theouter-glass contacting surface IE, and the screws 46 are then tightenedto hold the members in the desired relation. The resiliency of this sashis had through the medium of the resilient bracket 20, and also throughthe inner glass contacting member which may be formed of rolled metal ofa thinner gage than is used in the outer sash. It will thus be seen thata compound resilient sash is afforded by this form, a certain portionlofthe flexibility being had in the resilient bracket 20, and the remainderbeing derived from the inner rolled glass contact ing section.

In the form shown in Figure 3, the inner and outer sash members includeupright portions 50 and 5|. The outer sash member has a glass engagingportion 52 which is in a plane offset from the main upright portion 56.The resilient ccnnecting bracket in this instance is made separate frombut is operatively integral with the outer member, and'includes anupright part 53 having an offset end portion 54 which bears against theouter glass contacting part 52. The upright portion 53 is held againstthe upright portion of the outer sash 50 by any suitable means, such asears 55, struck up from the base of the outer sash and received insuitable holes in the bight portion 55 of the resilient bracket. Similarto the other form of bracket shown, there is provided an inwardlyextending shoulder E'I-from which are struck the wedge portions 53.

An intermediate bracket 59is provided, and, together with the inner sashmember 5|, is adapted to be fixed to the frame of the window 'as byscrews 60. It will be seen that this form of sash seats in a groove onthe window opet'i-- ing, the top of which is substantially flush withthe top of the inner sash member. The inner sash member has a gutterportion 6| and a glass contacting surface 62. It will be seen that inthis instance, as in the form of Figure 2, when it is desired to set theglass, the desired pressure is exerted from the outside, and the settingscrews 6| tightened down to retain the glass in its adjusted po-sition.

' In this form, as'well as in Figure 2, the gutters 4| and 6| serve theadded function of conduits for condensation occurring on the innersurface of the glass, thus keeping this moisture from running into theshow window with the possible injury of goods disposed therein.

Insomeinstances it is necessary to set the glass directlyagainst a framemember. This is particularly true of members adapted to be used with theside and head jambs of a window opening. A form; of the inventionadapted for this work is shown in Figure .4 andcomprises an outer sashmember 10 having an offset glass contacting flange 1 a horizontal part12 and a downwardly extending foot portion 13. The resilient 'member 14in this instance ,iscontinuous throughout the length of the sash and isfastened directly to the window jamb by suitable means, such as a screw15. The shoulder part 74 of the resilient member has the same wedgeshaped members it struck therefrom which are adapted to be engaged by awedge shaped nut Tl coacting with a screw '18 to hold the sash inadjusted position. It will be seen that the shoulder part of theresilient member is offset from the uppermost part i 19 of the bracketand is connected therewith by a curved portion;j,so asto-afford adefinite line of flexure about which the member may give to pressureexerted on the glass.

It will be appreciated that while the bracket members have beendescribed as discontinuous, they may readily be made continuous, as thatshown in the device disclosed'at Fig. 4.

Obviously numerous other modifications may be made in the dispositionand form of the various coasting parts'without departing from the spiritof the invention as defined in the appended claims.

What I claim is:- v

1. A sash for holding glass, comprising an inner sash member, an outersash member, a U-shaped resilient connecting bracket for said sashmembers, the free ends of said bracket being disposed outwardly in aplane offset from the night portion of said bracket, and means to fastenthe free ends of said bracketto sa'id sa'sh members in adjustedposition.

are established, and means to adjustably fasten said free 'ends'to saidsash members.
